The heat released when 1.00 g of ethanol (Mr = 46.0) undergoes complete
combustion is 29.8 kJ
What is the heat released by each molecule, in joules, when ethanol undergoes
complete combustion?
(the Avogadro constant L = 6.022 × 1023 mol–1
)
does anyone know how to get to the answer of 2.28 x 10^-18 ?

Find the heat released when one mole of ethanol undergoes complete combustion and then divide that number by number of molecules of ethanol in one mole of ethanol. The final answer (2.28 X 10^-18) is in J (per molecule) whereas the enthalpy change of combustion is given in kJ mol-1.
